GRAIN-CAR DOOR.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed January 25.1905. Serial No. 242,637-

To all whom, it may concern:

Be it known that I,WILLIAM H.MCMACH-EN, a citizen of the United States,residing at Superior, in the county of Douglas and State of Wisconsin,have invented certain new and useful Improvements in Grain-Car Doors, ofwhich the following is a specification.

My invention relates to the construction of grain-car doors and themeans for fastening doors in position, and has for its object theprovision of a door that is grain-proof and that is provided with simpleand easily-0perated means for fastening the door in position.

My invention will be described in detail hereinafter and illustrated inthe accompanying drawings, in which Figure 1 is a view of a fragment ofa car, showing the inside and the door in position and locked; Fig. 2, asimilar view of the exterior of the car and door in a locked position;Fig. 3, a horizontal sectional view of the door and'casing; Fig.4,a viewshowing the means for locking the sides of the door; Fig. 5, a de- Itail view of one of the side-locking means Figs. 6 and 7, detail viewsof the eccentric for securing the bottom of the door; Fig. 8, a

View of the plate for closing the small opening in the door, and Fig. 9a fragmentai view pif the edge of the bottom of the door and the cor.

In the drawings similar reference characters indicate correspondingparts throughout the several views.

A represents the side of the car, B the doorcasing, and C the fioor,having a groove 0' therein across the inside of the door. On each sideof the casing B is secured a metal strip D, which is bent so as to forma V- shaped bead d. p

E represents the door divided in two unequal portions and securedtogether by hinges F on the inside of the door, while G representshandles on the outside of the door for manipulating it. The ends of thedoor E are grooved, as shown at e, to receive the beads d, and the edgesslotted, as shown at H,

to receive the links I, secured in eyebolts i in casing B, J being keysto fit into the protruding ends of links I.

K represents wear-plates on the ends of the door having their outeredges turned outwardly, so as to form a flange 7c to hold the keys J inplace.

The bottom of the door fits into groove 0 and is locked to the floor bymeans of links L,

mounted in eyebolts Z, secured to floor 0, and eccentrics M, journaledon the door by means of shafts N, which have on their other ends ahandle N for rocking the shafts. The edge of each eccentric M isgrooved, as shown at m, to receive the link L in looking the door, theedge of the disk nearest the shaft N being smooth and tapered to anedge, as shown at m, so as to insure the link dropping off of theeccentric in unlocking the door.

0 represents angle-iron guides at the lower end of the door.

A small hole P is provided in the door. for extracting the grain beforethe door is removed, which is covered by a plate Q, having slots in eachend adapted to fit staples R on the door, the plate being held inposition by keys S.

In operation the door is secured in position by swinging the links Iinto slots H and inserting the keys J into the protruding ends thereofand by securing the links L on the eccentrics M. When the car is loadedwith grain, it will be readily seen that the beads 61 and grooves e andthe bottom of the door fitting in groove 0 in the floor of the carprevents the escape of the grain. To remove the contents of the car, theplate Q is first removed from the hole P, which allows sufficient grainto run out to permit the insertion ofthe operators arm in the opening Pto remove the keys J from the lower sectlon of the door. The handles Nare then operated to turn the eccentrics M from engagement with thelinks, and the lower part of the door may be swung inwardly andupwardly, so that the contents of the car may be got at by the operator.Should it be desired to remove the Whole door from the casing, the keysJ in the links I in the upper section of the door should be removed.

It will be readily seen that the links I permit the swinging of the dooron hinges F, which could not be done by having fixed studs withouthaving the slots I-I so large that the fasteningof the door would beinsecure. Having thus described my invention, what I claim is 1. Incombination with a grain-car and door, links secured in the floor of thecar inside of the door, and eccentrics ournaled on the door having theedges of their widest part provided with grooves to receive the linksand the edge of the narrowest part tapered, substantially as shown anddescribed.

2. In combination with a grain-car and its door-casing, links secured inthe sides of the casing and also in the floor of the car, a door havingslots in its ends to receive the links in the casing, and eccentricsjournaled on the door to engage said links, said eccentrics having theirwidest parts provided with grooved edges and the narrowest part tapered,sub stantially as shown and described.

I 3. In combination with a grain-car and its door-casing, links securedin the sides of the casing and also in the floor of the car, a doorhaving slots in its ends to receive the links in the casing, keys to fitin said links, and eccentrics journaled on the door to receive saidlinks, said eccentrics having their widestparts provided with groovededges and the narrowest part tapered, substantially as shown anddescribed.

4. In combination with a grain-car and its door-casing, vertical beadson the sides of said casing, links secured adjacent to said beads, thefloor of the car having a groove adjacent to the door-casing, linkssecured to the floor adjacent to said groove, and a door having groovesadjacent to its side edges to fit the beads on the casing and slotted toreceive the links on the casing, the bottom of said door adapted to seatin the groove in the floor, and eccentrics journaled on the door andadapted to engage the links secured to the floor, said eccentrics havingtheir widest parts provided with grooved edges and the narrowshapedbeads on the casing and the end of the door slotted to receive the linkson the casing, a strip of metal secured to the sides of the door andturned outwardly to form a flange at each end of the door, keys adaptedto seat in the ends of the links protruding from the slots in the door,the bottom of the door adapted to seat in the groove in the floor,eccentrics j ournaled on said door and having the edge of their broadpart grooved to receive the links secured to the floor, the narrowpartsv of said eccentrics being tapered, an opening in the door, and aplate adapted to be secured over said opening, substantially as shownand described. v

In testimony whereof I hereto afiiX my signature in the presence of twowitnesses.
